SPECIFICATION forming part of Letters Patent No. 514,577, dated February13, 1,894.

Application filed March 17, 1893. Serial No. 466,419. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOHN B. VVARING, of the city, county, and State ofNew York, have invented a certain new and useful Improvement in Machinesfor Cutting Pipes, of which the following is a specification.

My improvement relates to machines intended for cutting pipetransversely to its length.

The object of the improvement is to produce a more efficient machine ofthis class, which will be adapted for the cutting of cast iron, as wellas other pipe, even while thev pipe is in position for use, and withal,shall be of very simple construction.

I will describe a machine embodying my improvement, and then point outthe novel features in the claims.

In the accompanying drawings, Figure 1 is an end view of a machineembodying my irnprovexnent. Fig. 2 is a transverse section of thesame,taken as indicated on the dotted line, 2, 2, Fig. 1. Fig. 3 is avertical section taken as indicated by the line 3, 3, Fig. 2. Fig. f1 isa top view of the machine. Fig. 5 is arear view of a gear section usedin the machine. Fig. 6 isafront view of said gear section. Fig. 7 is aside view of a pinion for engaging with the gear section, and shown inFigs. 5 and 6, and a complementary section, of the latter. Fig. 8 is arear view of another gear section. Fig. 9 is a front view of this gearsection. Fig. 10 is a side view of a pinion for engaging with the gearsection, illustrated in Figs. 8 and 9 and the complementary section, inthe latter. Fig. 11 is a view similar to Fig. 1, illustrating amodification. Fig. 12 is aview similar to Fig. 2, and illustrating thesame construction as Fig. 11. Figs. 13 and 14 are back views of portionsof two gear wheels.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the main frame of the machine. It may be made of anysuitable material, as, for instance, cast iron. It will probably be madein the form of a hollow cylinder or ring. In any event, its innersurface will be most advantageously made separate. It is composed of twosections o.' c?, which, as here shown, are semi-cylindric and areahutted end to end. At or near their abutting inner ends are laterallyextending lugs @,'and through them pass screw bolts c3, whereby the twosections are fastened together. The advantage of this constructionarises from the facility aiforded for applying the frame A to a pipewithout being obliged to slip it over the end of the pipe.

Viithin the frame A are clamps B1 B2 B3 B4 for fastening the frame A.upon a pipe. These clamps consist of blocks iitted'to the frame A so asto be adjustable radially. On their inner ends they are provided withteeth, the better to enable them to grip a pipe. As here shown, they areprovided on their front sides with radial grooves i) which are iitted roradial ribs a4 formed on the frame A. At the bottom of each groove h isa lug b', and at the top of each rib a4 is a lug a5, which eX- tendsover the plane of a lug b. By the use of these lugs b a5, these blocksare limited in their inward movement.

C C2 C3 C4 are radially arranged screws engaging with tapped holes inthe frame A and having their inner extremities titted to bearings formedin the outer portions of the clamps B. By manipulating these screws, theclamps may be adjusted and caused to forcibly impinge against a pipe.

D D2 D3 are radially arranged cutters fitted in slide-ways formed bypairs of lugs d' d2 extending from the front face of a gear wheel D.This gear wheel is composed of two sections (13h14, each of which issemi-cylindric; the two having their ends abutted together. Theadvantage of making this gear wheel in two sections is to enable it tobe fitted around the pipe sidewise as distinguished from being slippedover the end of a pipe. Motion is imparted to the gear wheel D whichcarries the cutters D DZD3 by means of a pinion D4 mounted upon a studor shaft E fitted in a bearing formed in a radially extending boss whichis integral with the frame A. The pinion D4 is keyed to the stud orshaft so as rotate with the latter.

F designates another gear wheel which is composed of two sections f f2.Itis made of two semi-cylindrical sections abutted together end to endfor the purpose of facilitating its application to a pipe. Each sectionof the gear wheel F is provided with a IOO laterally extending rim orflange f on its front side and this enters and engages with a grooveformed in the frame A, it being held in said groove by a tongue f3extending from the frame A adjacent to a shoulder formed on the gearsection. Each section of the gear wheel D is provided with a rim orflange de which engages with a groove formed in a corresponding seetionofthe gear wheel F, and the latter has a shoulder d? that holds the rimor flange d6 of each gear Wheel section D in engagement with the saidgroove inthe corresponding gear wheel section F.

F is a pinion keyed to the stud or shaftE and engaging with the gearwheel F.

It will be observed that the teeth of the gear wheel sections are ontheir forward sides so as to engage with the pinions D4 and F. As thegear wheels are made in semi-cylindrical sections and the frame A issimilarly made, the gear wheel sections can be inserted end wise in thesections of the frame and rotated or moved longitudinally kinto place.The gear wheel F is provided near its periphery with a flange composedof eccentric segments f5. The relation of the gear wheels F and D andtheir pinions F and D, are such that the wheel F rotates more slowlythan the Wheel D. The difference in speed, is, however, very slight andsolely for the purpose of causing the eccentric segments f5 of the gearwheel F to operate upon the end of the cutters D D2 D3, so as to forcethe latter inwardand cause them to cut into and through a pipe.

On the shaftE is affixed alarge gear wheel G that engages with a pinionI-I mounted on a shaft H that is supported in an arm I. The arm I has atone end a collar which is fitted to the lug in which the bearing for thestud or shaft E is formed. Consequently, this arm is free to revolve. Itcan be clamped in any desired position by tightening the screw-bolt I',the arm being made with a bifurcate portion to permit ot' its beingclamped or loosened. One end of the shaft Irl is shown as being squaredfor the purpose of receiving a crank.

It will be seen thatI have produced a very simple machine which can beapplied side- Wise around a pipe, and therefore used upon a pipe alreadyin position.

In Figs. 1l and l2, I have illustrated a modification, which consists inthe use of a worm H5 instead of pinions F D4. In this example of myimprovement, the teeth of the gear wheels D and F will be slightlymodified, to enable them to engage with the thread of the worm.

In Figs. 13 and 14, I have illustrated means for securing the properalignment of the two sections, of which each of the gear wheels D F, iscomposed. Looking first at Fig. 15, s

tions and to combine a pin s therewith, is to.

first form the Wheel entire, and before it is divided into semi-circularsections, to bore in a direction, parallel with the axis of the wheel,the recess, which is required for accommodating the pin s. Then the pins maybe inserted. Afterward the wheel may be out in two, on oppositesides of the pin. Finally, the pin may be secured in place by having apin s passed, transversely, through it and into the end of one of thesemi-circular sections of the wheel. If the abutting ends of the twosections of thegear wheel are illustrated, there will be locks or keys,consisting of two such pins, as the pin s, for holding the twosemicircular sectionsin alignment.

In Fig. 14 I have shown a pin or key s2, shaped like the keystone of anarch. This may be applied in the same manner as the pin s, and similarlysecured in place after the cuttingof the gear wheel into the twosemicircular sections, by introducing a pin s3.

Nhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In a machine for cutting pipes, the com bination of an internally,cylindrical frame of separable sections, cutters, a wheel for operatingthe cutters, and also made of separable sections, a similarly made wheelfor carrying cutters, and means whereby one of the Wheels will be drivenfaster than the other, substantially as specified.

2. In a machine for cutting pipes, the combination of an internally,cylindrical frame, cutters, a wheel 4for operating cutters, a wheel forcarrying cutters, and means whereby one of the Wheels will be drivenfaster than the other, substantially as specified.

3. In a machine for cutting pipes, the combination of an internally,cylindrical frame, cutters, a wheel carrying cutters, a cutteroperating, or pinion Wheel, provided with eccentric segments f5 andmeans for operating said wheels, so that one will rotate faster than theother, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
